Wanamaker, Philadelphia, Pa., assignor to Procter & Schwartz,Incorporated, Philadelphia, Pa., a corporation of PennsylvaniaApplication May 12, 1937, Serial No. 142,309 3 Claims. (Cl. 223-75) Thisinvention relates to hosiery clamps for stocking form A, with laterallyextending ears use with the stocking forms employed in hosiery 5,projecting from opposite edges respectively drying machinery of allkinds and particularly of the stem 3 to clamp the form therebetween thattype of machine disclosed in the prior United by means of clamp screws8.

The T-shaped supporting members include As disclosed inthe above noted patents each vertical shanks 22 which are slidablymounted in of the stocking forms A is mounted In a carrier the standardsI, 1 respectively. Each shank 22 which is advanced along a predeterminedpath in is provided with two pair of lat rally extending 40 a coursepartly within and partly outside a suitprojections or pins 23, 23 and24, 24. The pair of able drying chamber. pins 24, 24 are locatedadjacent the lower or free In that portion of the travel lying outsidethe end of the shank 22, while the pins 23, 28 are drying chamber driedstockings are removed located along said shank intermediate the pins 24from the forms emerging from the drying chamand the cross bar I 9. herand damp stockings are placed on the forms The pins 23, 23 and '24, 24are adapted to slide prior to the entrance of the forms into the dryinvertical grooves or guideways 25, 25 formed ing chamber. in oppositelydisposed relatively spaced portions Each form A is removably secured ina head I 28, 26 of each standard I and which provides a of a spindle 2which latter is adapted to be channel 21 between said portions in whichthe 50 mounted in a carriage (not shown) operating on shanks 22 arelocated. a track in the drying machine. At the upper and lower endsrespectively of In the present instance, the head I is prothe guideways25, 25 are provided with stop abutvided with a central stem portion 3having a ments 28, 28 and 29, 29 which limit the moveslot 4 adapted toreceive the lower end of the ment of the shank 22 in the space 21 by theupper 55 pins 23 on the shank engaging the top abutments 23 and thelower pins 24 engaging the lower abutments 23.

The lower end of each shank 22 is provided with a stud on which isrotatably mounted a roller 3|. The rollers 3|, 3| are adapted to engageand ride against rails 32, 32 and 33, 33 which are retained in fixedposition along the path traveled by the forms A.

The guideways 25, 25 are provided with intersecting passages 34, 34through which the lower pins 24, 24 are adapted to pass while the pins23, 23 are retained within the guideways 25, 25 and function as fulcrumsfor the shanks 22, 22 whereby the lower ends of the shanks swingoutwardly and the cross bars and the clamp members "I, I0 carriedthereby swing inwardly to bring the clamp members III, In flatly againstthe opposite faces of the form A into contact with the welt of thestocking mounted on said form.

As shown in Figs. 1 and 2., the clamps Ill, l0 normally lie in a lowposition within the recesses B, 8 while a dry stocking is being removedfrom the form A and a wet stocking B is being placed thereon.

The boarder pulls the welt C down on the board or form A intoapproximately the first position shown at the left hand side of Fig. l.

The rollers 3|, 3|, as the form A moves along toward the right, firstengage the inclined rails 32, 32 which raises the T-shaped supports ofthe clamps Ill until the form reaches the third position in Fig. l, atwhich the pins 23, 23 on the shank 22 are in engagement with the upperabutments 28, 28 on the standards I, I and the pins 2'4, 24 are in linewith the cutouts 34, 34 in the guideways 25, 25.

The rollers 3|, 3| then engage ribs 35, 35 on the rails 32, 32 and therails flare outwardly. As the form continues to move the flaring of therails, from the position shown in Fig. 3 to the position shown in Fig.4, causes the shanks 22, 22 to swing outwardly at their lower ends,causing the clamps |0, ID to engage the stocking welt C flatly on eachof the opposite faces of the form A.

The rollers 3|, 3| then move under the rails 33, 33, as shown in Figs. 1and 5, which moves the shanks 22 and the clamps l3, l0 downwardly, theclamps still being held firmly in contact with the stocking welt C byribs 36, 36 on the lower sides of the rails 33. The downward movement ofthe clamps Ill, ||l pulls the welt C of the stocking downwardly whichremoves wrinkles from the leg portion of the stocking and sets" thestocking on the form.

In the course of travel of each form through and out of the dryingchamber the clamps l0, l0 may be held continuously in contact with thewelt C in which case the moisture evaporating from the welt passesthrough the wire mesh pad H and grid frame which supports said pad, orthe clamps l3, "I may be released immedately after setting of the welt Con the form A.

In either case the rollers 3|, 3|, to release the clamps, engage anotherinclined rail, similar to the rails 32, which raises the shanks 2'2 andconverge to move the pins 24 back through the cutouts 34 into theguideways 25, whereupon the rails decline and lower the clamps Ill, Illinto the recesses 8, 3 for a repeat of the operation.

Preferably, the clamps H] are locked in contact with the stocking on theform A after the setting operation and during the whole of the dryingoperation. This locking is accomplished by the guide pins 24, 24 beingmoved downwardly beyond the lower edges of the cutouts 34, 34 during thepulling down of the stocking by the rails 33. The rollers 3| ride oilthe rails 33, at the ends thereof, and the springs 23 rock the carriersof the clamps Ill slightly in the direction opposite to that in whichthe shanks 22 were previously rocked by the flaring of the rails 32,until the guide pins 24 come to rest against the outer surfaces 31 ofthe standards which in tersect the lateral passageways formed by thecutouts 34 and which function as looking shoulders for the pins 24, 24.

The clamps I3, I0 are prevented from moving downwardly to an excessiveextent by the lower edges of the clamps ||l coming to rest on the upperedges of the stem 3 and ears 5.

The construction disclosed above and in the accompanying drawingsprovides for movement of the clamps l0, III to positions below the loweredges of the forms A, out of the way of the stocking boarders whenplacing stockings on the forms, while still keeping the clamps withinthe shortest possible radius with respect to the axis of the spindles 2about which the forms A and their complementary clamps, etc. revolve intheir passage along their circuit of travel in the drying machine, whichmakes it possible to reduce the clearances for the forms at points inthe circuit where the forms may be required to turn while the clamps arein inoperative positions with respect to the form. This permits theforms to be run closer together in the machine which increases thecapacity of the machine without increasing the size of the machine.
